BMW 218i vs Mercedes-Benz AMG GT

What's the difference?

The badge might say one thing, but the 2 Series Gran Coupe sticks to the time-honoured template of being a compact yet comparatively practical three-box, four-door sedan, complete with a big boot.

More importantly, it drives and behaves like a BMW – which means sufficient-to-strident performance depending on grade, athletic dynamics and pleasing refinement on one hand, as well as a stiff price and a hard ride on the other.

A true BMW in name and nature, then..

The GT63 4Matic+ is a breathtaking example of everything that Mercedes-Benz and AMG are.

Ferociously fast, incredibly agile and superbly sophisticated, it should be on anybody’s shortlist, if that also includes a Porsche, Aston Martin, Maserati or even a Lamborghini. And it’s definitely much more than yesterday’s SLC ever was – for similar money in today’s terms, as it turns out.

But, around Tasmania’s glorious roads at least, the Mercedes-AMG lacks the ride comfort and road noise isolation to be a fully-rounded-out GT, and that’s a disappointment for a brand with such formidable history in making such cars.

BMW is calling the F74 a new-generation 2 Series Gran Coupe, and there have been obvious and even profound changes throughout and underneath, including to some of the sheetmetal.

But this is not an all-new car by any stretch, with the glasshouse, doors and roof amongst many other body items carrying over from the F44.

That now remarkably Kia Cerato-esque nose ushers in new LED lighting motifs and an updated kidney grille, but whether they sit easily with the rest of the car is debatable. Redesigned tail-lights, different colours and new alloys make up the majority of the exterior changes.

Betraying the latest 2 Series Gran Coupe’s newness claims are near-identical dimensions, with that redesigned front end and bumpers contributing to a 20mm increase in the F74’s 4546mm length, while revised suspension and damper settings help account for the 25mm boost in height (to 1445mm). The BMW’s 1800mm width and 2670mm wheelbase remain the same.

There’s a higher level of newness to be found inside.

This is still clearly a Mercedes AMG GT coupe, like the 2014 C190 original, but a ground-up redesign sees it subtly yet significantly altered.

Some 270kg heavier than before, the larger-in-every-dimension body combines aluminium, steel, magnesium and fibre composite materials for improved rigidity and a lower centre of gravity. Length (4729mm) and wheelbase (2700mm) have been stretched by 177mm and 70mm respectively. Width (1984mm) and height (1352mm) are also up.

The nose treatment is similar to before, especially with the bulgy bonnet and signature vertical slatted grille fitted. These, combined with the LED digital headlight shape effect, is reminiscent of, but far-better executed than, the goofy-looking MG5’s face.

Underneath, it's an all-new platform shared with the SL, with the rear transaxle of the old car replaced by a permanent AWD system, leading from 46:54 front/rear weight distribution to 50:50 as a result.

That aggressive, exaggerated cab-backward/ultra-long bonnet silhouette that visually connected it with the SLS gives way to more-conventional and practical coupe proportions that is striking if not especially original, since they do look quite 911-esque. Along with the longer wheelbase and wider tracks, the result allows for two small rear seats to be fitted, while liftback cargo access remains.

Similarly, in the name of way-more usable interior packaging, Mercedes-AMG says it pushed the driving position nearly 180mm forward compared to the previous GT. Let’s see what that all looks like inside.

During the media presentation at its launch, BMW described the 2 Series Gran Coupe as being almost as large as a 1990s E46 3 Series, and it is in all major dimensions except wheelbase.

Plus, being a front-drive-biased/transverse engine proposition instead of rear-wheel drive should make it roomier than the F74’s iconic ancestor.

The sense getting in is that this is certainly not too low or cramped as per a more-traditional coupe, with plenty of space for legs and shoulders, while even the optional sunroof fitted to our 218 left us with headroom to spare.

The redesigned dash is a visual and operational treat, with crisp, clear instruments, a logically presented and intuitive centre display screen offering fast and easy operation, excellent ventilation and ample storage. Full marks here.

Better still, attaining the perfect driving position is possible for most people, on brilliantly supportive front seats. This is the stuff BMW does right.

Improvement suggestions for the next update? Some people may complain about the somewhat less-than-premium feel of some of the lower-lying plastic trim; not everybody will love the swatches of colour stitching (we love it); why does the steering wheel have to be so wide-of-rim? Side and rear vision is restricted by fat pillars, rising shoulder lines and a shallow rear window; and there is quite a bit of road noise that enters the cabin at speed.

Still, even the back seat is sufficiently spacious for most users, with the sole exception of taller folk having to negotiate a sloping rear roofline. If you’re below 180cm, this should be fine. Most amenities minus overhead grab handles are also fitted.

Further back, the boot is surprisingly accommodating, with 430 litres of cargo capacity that’s enhanced by a 40:20:40 split-fold backrest, and the aperture should be big enough for bulkier loads, but the lack of a spare wheel will be bad news for many buyers. The supplied tyre-repair kit is just not good enough.

But, you know what is good enough? The engines BMW builds, that’s what.

The first impression inside is that of space, despite the falling roofline and coupe-like upsweep of the side windows and you look back. While, again, similar to a 911s, a kink at the door gives the GT a unique character.

Even larger people will appreciate the generous amounts of room up front, with space to stretch, sat in sumptuously comfy bucket seats. Note that the standard ones are better than the racier but firmer Sports versions.

The driving position is perfect, ahead of a dashboard that is very typical modern Mercedes in appearance and layout.

To that end, the tablet-style integrated touchscreen (11.9 inches) is clear, fast and intuitive once time is taken to learn it. And points are also won for the multi-configurable electronic instrumentation, that allows for a variety of screens, including track, classic and minimalist views.

The trademark turbine air vents, the quite beautiful material and trim finishes and just the general solid feel are further typical contemporary Mercedes cabin treatments, as are the excellent ventilation and ample storage options.

And while rear vision isn't great, that's what cameras are for. It's all pretty much on brand.

It is a shame, given how elevated the Mercedes-AMG engineering is underneath, that the GT’s interior look and ambience is so similar to those of a (albeit higher-spec) C-Class or GLE. It's simply not as special as some of the company’s previous sports cars.

More annoyingly, the ride is too firm and bumpy for a GT, and this has the unhappy effect of provoking random rattly trim sounds within the cabin. It’s a bit like scrunched-up cellophane. In a $420K (as tested) Merc, that’s very disappointing, especially as it can be heard over the copious amount of road and tyre noise droning through, particularly on coarser bitumen surfaces.

Further back, the rear seat is strictly two-plus-two, and nobody over 150cm tall is recommended to travel there by Mercedes itself. That sloping roofline is the culprit. That said, brief trips with a bowed head are possible, as the fixed cushions and split-folding backrests are actually surprisingly comfy. But only for short journeys. Kids should love it though, and the second row does open up the GT’s usefulness enormously.

As does a near-doubling of the AMG’s cargo capacity, jumping 146 litres to 321L with backrests erect, to a whopping 675L (+325L) in two-seater mode. The flat floor is accessed via a large electrically-operated liftback door, offering quite a large aperture for easy loading/unloading.

Having no spare wheel helps here, with a tyre inflation kit included in lieu of that.

Meanwhile, at the front, under the bonnet, things have definitely changed for the better as well.

Starting from $370,400 (all prices are before on-road costs), the Mercedes-AMG GT63 4Matic+ is priced and positioned as something of an eagle amongst some pretty delectable doves, given its combination of four seats, 430kW of power, 800Nm of torque and four-wheel drive.

No rival equivalents can match the Mercedes on paper. The 398kW/610Nm 911 Carrera 4 GTS T-Hybrid offers less power but starts from $400,000-plus. The 410kW/650Nm GranTurismo Trofeo begins at $450K, the 500kW/800Nm DB12 from $455K and the 404kW/470Nm Continental GT from $460K.

Only the 460kW/750Nm BMW M8 Competition comes closest to the Mercedes-AMG, from $380K.

Side note, today’s GT is only slightly more expensive than what the 450SLC was nearly half a century ago when adjusted for inflation.

And, just like with that classic old Benz, it shares much with the brand’s legendary SL convertible stablemate – including, in this case, standard all-wheel drive and active rear-axle steering… aka 4WS to select third and fourth-generation Honda Prelude owners out there.

What else does $400K-plus buy you? As you’d expect, the GT63 4Matic+ comes choc-full of standard equipment, much of it typical of the luxury coupe breed, with leather-covered and electrically operated everything.

How about a front-axle lift system with GPS-enabled memory that automatically raises the GT’s nose to help clear bumps and then remembers to do so next time?

There are climate-controlled AMG sports seats with inflatable bolstering and massaging functionality, a fixed glass roof, a head-up display, augmented-reality satellite navigation, 360-degree surround views, performance telemetry data as part of an extensive multimedia system, an 11.9-inch portrait touchscreen, 11-speaker Burmester audio, a handsfree-powered tailgate, 21-inch alloys and cutting-edge driver-assist safety tech. More on that in the Safety section below.

Then there are the myriad option packs, bumping the GT63’s price up towards $500,000. These include a $2.7K seat trim package; a $10K AMG Night Package that adds darker trim treatments (often where chrome was); an aerodynamics package with fixed spoiler replacing the standard active spoiler; a $2.6K AMG Performance Seat package; a $13K Carbon Fibre package and $13.2K Ceramic Brakes.

Now, while the new GT does ditch the previous model’s unique rear transaxle spaceframe pioneered by the gull-winged SLS of the early 2010s, the resulting longer wheelbase and shorter overhangs do provide less outlandish and more practical design.

Let’s check that out in more detail. 

Three F74 powertrain choices are available for Australia in 2025. And none even remotely reflect what their respective badges imply on the boot.

The 218, for instance, is not powered by a 1.8-litre engine, but BMW’s long-lived B38 1.5-litre three-cylinder turbo petrol unit. Making 115kW of power at 6500rpm and 230Nm of torque between 1500rpm and 4600rpm, drive is channelled to the front wheels via a seven-speed dual-clutch transmission (7DCT).

With a kerb weight of 1420kg, the 218 has a power-to-weight ratio of 81kW per tonne, helping it achieve the 0-100km/h sprint time of 8.6 seconds, on the way to a 230km/h top speed.

Not enough? The 220 features the ubiquitous B48 2.0-litre (not a 2.2-litre) four-cylinder turbo petrol engine/7DCT combo, pumping out 150kW at 6500rpm and 300Nm from 1450-4500rpm. Tipping the scales at 1525kg for 98.4kW/tonne, its 0-100km/h time is 7.3s and top speed is 250km/h.

Want more? Stretching to the M235 xDrive sadly doesn’t mean a 3.5-litre in-line six, but a modified B48 2.0L/7DCT duo, delivering 233kW at 6500rpm and 400Nm from 2000-4500rpm to all four wheels. Result? Weighing just 50kg more than the 220, it boasts a heady 148kW/tonne, for a 0-100km/h of just 4.9s and a 250km/h v-max.

As with all of the UKL2/FAAR transverse-engine front-to-AWD platform models from non-electric Minis through to sub-X3/3 Series BMWs, you’ll find MacPherson-style struts up front and a multi-link independent rear end out back.

If you’re reading this outside of Australia, you may notice that none of the current F74 models offer mild-hybrid tech, in contrast to their European counterparts. And don’t go expecting any manual gearboxes either, unfortunately.

There’s a plaque signifying which engineer “handcrafted” the GT’s engine – in this case, the famous M177 in 3982cc, 4.0-litre twin-turbo intercooled V8 petrol guise.

Delivering 430kW of power at 6500rpm and 800Nm of torque from 2500-4500rpm, it sends drive to all four wheels via a nine-speed multi-clutch transmission (dubbed MCT in AMG-speak), catapulting the GT63 4Matic+ from 0-100km/h in just 3.2 seconds, on the way to a top speed of 315km/h.

How does it do that?

With AWD, the GT is now nearly 15 per cent heavier than before, but it still manages a punchy 218kW/tonne. Active aerodynamics over, inside and under a more-rigid body structure also helps.

The AMG 4Matic+ AWD system goes from 50/50 front/rear, to 100 per cent rear, variable torque distribution according to conditions and settings, and backed up by an electronic limited-slip differential. Among the many driving settings are Race Start, Drift Mode and good-old Comfort, if it all becomes too much.

Also keeping all that performance in check is a high-performance composite brake setup with improved cooling for faster responses.

Interlinked active roll bars improve body control, the five-link independent suspension features adaptive dampers for a softer ride.

And, as for that 4WS tech, the rear wheels steer opposite to the fronts at up to 100km/h (by some 2.5 degrees) for tighter and tidier handling, or 0.7 degrees in the same direction above 100, for greater stability and road-holding.

Its effect on the way this near-two-tonne coupe zigs and zags around corners is something you need to experience to really appreciate.

OK, so is the 2 Series Gran Coupe cheap to run?

BMW reckons the 218 and 220 will average 6.3 and 6.7 litres per 100km, which means combined average carbon dioxide emissions ratings of 143 and 152 grams/km respectively.

Filling the 49L fuel tank with 95 RON premium unleaded, that translates to around 775km in the 218, and 730km in the 220 between refills.

Predictably, the M235 xDrive uses more, at 7.7L/100km for a CO2 rating of 176g/km. That’s a distance of about 635km.

Over our launch run, which took us from Sydney’s Circular Quay to Wollongong, the 218’s trip meter was reading in the high 8s and about 10 for the M235.

Actually, the GT’s economy isn’t horrendous considering how fast it can go.

Even blasting a few times around beckoning country roads, we managed an indicated 13.0L/100km, which is an improvement on what Mercedes-AMG says the GT averages the 14.6L/100km average that Mercedes-AMG officially states.

That translates to a carbon dioxide emissions rating of 334g/km.

Using 98 RON premium unleaded petrol, an average of just under 480km between refills of the 70L tank is possible. The urban run sees consumption rocket to 21.8L/100km (for just 321km of range), or 10.4 out on the highway run, meaning that over 670km is possible should you decide to drive in a docile manner.

Earlier, we mentioned that the 2 Series Gran Coupe is way more expensive than fine alternative sedans like the Mazda3 and Toyota Corolla.

And while that still stands, there is a remarkable solidity and refinement difference between those and the BMW that helps justify the premium. And nowhere is this more evident than from behind the wheel.

Sat on body-hugging seats and clutching that (too chunky) steering wheel, there is a sense of sporty occasion, backed up by quality trim and an aroma of expensiveness.

For a turbo three-cylinder car weighing 1.5 tonnes, the 218 does a lot with a little, offering spirited off-the-line acceleration and pleasingly lag-free throttle responses at lower speeds. You’d never call it fast, but it is a quick point-to-point urban mover. Only the unavoidable three-pot thrum lets you know you’re in the lowest mechanical spec. And, also, the delay at freeway speeds in building momentum when overtaking.

Which is why, for less than five per cent extra, the 220 with the 2.0-litre four-cylinder turbo would probably make a better buy. Sadly, that isn’t on sale yet in Australia, so we missed out on driving it during the Sydney launch. But in the scores of other BMWs and Minis we’ve tested this in, it’s a cracking little powertrain.

Whether the big leap (nearly $25K worth) to the M235 is worth it depends on how fast you drive and how much you value/need AWD. This is a terrifically muscular machine, since it provides rapid performance via a tidal wave of power, even with the lightest flex of your right foot. On-point and on-brand, this fun and fiery flagship possesses the grand-touring spirit that the rakish design and tech-heavy engineering promise.

To that end, in both the 218 and M235, the steering makes the driver feel connected to the car, resulting in precise and controlled handling. The driver-assist safety tech is beautifully calibrated and nuanced in its intervention, and the brakes are second-to-none.

What is also on-topic for a BMW is the firm suspension, despite the adaptive dampers fitted as standard equipment.

It isn’t stiff or overly uncomfortable, but bumps are certainly always felt, and they’re accompanied by fairly constant road-noise drone over some surfaces.

As such, you’re constantly reminded that dynamic athleticism is the priority here, rather than sumptuous comfort. We’ve experienced much worse from BMW, but a magic-carpet ride isn’t what’s in store for the 2 Series Gran Coupe owner.

So, what’s our verdict then? The 218 is a rorty little tryer that never fails to involve the driver, while the M235 ushers in an elevated level of acceleration, grunt and grip. We suspect that the 220 will be the Goldilocks-zone happy medium.

For (largely) better as well as for (occasionally) worse, these drive and feel like a BMW should.

Nobody will drive the GT63 4Matic+ and think, ‘Oh, this is OK’, because its breadth of performance is phenomenal.

No matter which mode you're in, from Comfort through to track-tuned Race, the Mercedes-AMG blends forceful pace and commanding control without ever breaking a sweat.

Flex your right foot and the two-tonne coupe bounds into action like a giant on a mission, striding past posted speed limit signs in nanoseconds and way, way faster than the law will stand if diligence isn’t exercised.

And there’s no point relying on seat-of-your-pants sensations, either, because the chassis below embraces the road with an almost zealous devotion. Which is astounding, given how agile the four-wheel steering-enhanced handling is.

The 63’s super power is exactly that – it dulls your sense of speed. One tester admitted to exceeding 150km/h before noticing. An odd confession considering the sonic boombox that is the bi-turbo V8’s howl.

But jailbait performance is not even the 63’s most lingering joy. That would be its steering perfection, that delivers that rare trifecta of keenness, crispness and communication. The wheel feels eager and alive in your hands, even when powering between tight turns, backed up by sensational grip and control. How can a two-tonne GT handle so sharply?

Warm, dry roads were the order of the day, so we can’t tell you how the 4Matic+ permanent AWD system deals with wet or slippery surfaces, but the slick multi-clutch transmission, seamless torque-vectoring tech and sticky tyres more than cope with the 63’s formidable outputs.

So, that's the gushing part out the way, then.

Despite the adaptive dampers, rigid architecture and exquisitely sophisticated suspension, the ride is simply too stiff in Comfort mode, and downright jittery on some of the Tasmanian roads we tested on, for the 63 to be considered a true luxury grand tourer. It just isn't comfortable, luxurious or supple enough.

Plus, grippy as they are, the 21-inch wheels transmit too much road and tyre noise through to the cabin, meaning that the GT isn't as quiet as you'd hope. Add the aforementioned trim squeaks, and the expected cocooned silence isn’t always there.

The upshot is that the 63 possesses more of a sports car character than a luxury GT character. Great news if you're a 911 type buyer and are seeking a high-performance 2+2 alternative, but a disappointment if comfort and refinement are priorities.

Still, it is impossible not to be deeply moved by this Mercedes-AMG.

While the GT doesn’t score an ANCAP rating – probably because it’s too expensive to crash test – we’d wager that it would be above-average, given Benz’s track record as a pioneer in this field.

That’d due to the scores of active, passive and driver-assist safety features fitted, from multi-faceted autonomous emergency braking (AEB) and lane-support systems to Mercedes’ PRE-SAFE tech that anticipates a crash and then prepares the car for impact.

More specifically, the GT includes Active Lane Change/Keep Assist, adaptive high beam as part of its megapixel LED set-up, adaptive cruise control, Cross-Traffic Assist, Evasive manoeuvre support, an emergency services call-out system, 360-degree camera views, pedestrian protection bonnet and eight airbags.

In other Mercedes products of today, AEB operating parameters are 7-80km/h for vulnerable road users like pedestrians and cyclists, and from 7-250km/h for vehicle-to-vehicle, while the lane-keep support systems operate between 60-200km/h.

Finally, there are ISOFIX child-seat anchorages in the front passenger seat and two in the rear seats.

Here, however, is where BMW can do a bit better.

While the five-year/unlimited-kilometre warranty is where most premium brands are, it falls short of several Asian alternatives. Roadside assistance is for just three years and there is no capped-price servicing.

Service scheduling is also condition-based, meaning the vehicle will alert the driver when a service is imminent. This may not suit everybody, and we always recommend at least every 12 months or 10,000km, just to be on the safe side.

BMW does offer pre-paid service packs that take in basic maintenance for the first five years at $2369 or $3782, including brake-pad replacement, which works out to be about $475 and nearly $760 annually respectively. There is also a cap on mileage during that time frame: 80,000km.

What’s the GT like to own?

Mercedes-Benz offers a five-year/unlimited km warranty, with five years of roadside assistance. This is average for most mainstream and luxury brands, but superior to most sports-car makers like Porsche and Lamborghini.

Intervals are every 12 months or 20,000km, and while no capped-priced servicing is offered on the GT, pre-paid three-, four- or five-year service plans are available, ranging from $5165, $7700 and $8665 respectively.

Big performance demands big maintenance bills, it seems.
